Chicago, Oct. 30, 2025 (GLOBE NEWSWIRE) -- The global HER2 positive breast cancer treatment market was valued at US$ 8.56 billion in 2024 and is expected to reach US$ 18.67 billion by 2033, growing at a CAGR of 9.1% from 2025-2033.
The HER2 positive breast cancer treatment market is undergoing dynamic expansion, fueled by rising disease prevalence, increased awareness, and advancements in precision oncology. Characterized by the overexpression of the HER2 protein, this aggressive breast cancer subtype affects roughly 20% of diagnosed cases and shows higher incidence among younger patients, with nearly 30% of individuals aged 15 – 29 years testing HER2 positive. Diagnostic tools such as IHC and FISH play a critical role in identifying candidates for targeted therapies, which have significantly improved outcomes over the past decade.

The market is driven by rapid drug development, faster regulatory pathways, and the integration of artificial intelligence in treatment decision-making. Standard treatment typically involves surgery, radiation, and systemic targeted therapies such as trastuzumab and pertuzumab. These agents, used in combination with chemotherapy, have become foundational in both neoadjuvant and adjuvant settings. Yet, recurrence remains a challenge, often requiring advanced therapies like trastuzumab deruxtecan (Enhertu), tucatinib, and neratinib, each demonstrating promising results in previously treated patients.
HER2-targeted therapies are generating strong commercial performance, attracting sustained R&D investments from leading biopharma players. Enhertu was initially approved in 2019 for treating HER2 positive breast cancer patients. Daiichi Sankyo’s 2024 reported global sales for Enhertu were USD ~2.9 billion in 2024. Roche’s Perjeta also brought USD 4.5 billion in sales within the same year. Additional therapies like Tukysa also recorded significant revenue, reflecting a thriving market. These commercial successes are accelerating clinical pipelines, with companies such as Roche advancing next-generation candidates like RG6171 into late-phase trials.
However, high treatment costs remain a critical barrier. Herceptin is priced at approximately USD 1,674 per vial, and Perjeta costs around USD 5,534 per dose – resulting in high annual costs. In low- and middle-income countries, limited access, delayed diagnoses, and high out-of-pocket expenses make such targeted treatments inaccessible. The financial strain is compounded by indirect costs, highlighting the need for broader affordability and access to care.
Despite these challenges, the HER2-positive breast cancer treatment market is poised for sustained growth. With a robust pipeline and growing global focus on precision oncology, HER2-positive therapies are set to remain at the forefront of breast cancer innovation.

Technological Milestone: Opportunity in Personalized Medicine & Companion Diagnostics for HER2-Positive Breast Cancer
Relapse remains a significant challenge in HER2-positive (HER2+) breast cancer, with only 30% of patients responding to trastuzumab monotherapy and resistance often limiting long-term efficacy. Crosstalk between HER2, estrogen receptors (ER), and other HER family members add biological complexity, reinforcing the need for personalized treatment strategies.
In the era of precision medicine, therapeutic approaches are shifting toward escalation or de-escalation based on molecular profiling. As an understanding of HER2+ tumor biology advances, the field is moving beyond uniform treatment models. Emerging evidence supports dual inhibition of HER2 and ER pathways in co-expressing tumors, offering a promising route to improved outcomes.
The development of biomarker-driven, risk-adapted regimens, guided by companion diagnostics, is central to this transformation. These approaches enable more targeted therapies, minimize overtreatment, and create strong opportunities for innovation and market differentiation in precision oncology.
Global Breast Cancer Market: Regional Forces Driving Progress in Care and Innovation
The global breast cancer market is undergoing significant transformation, driven by regional advances in research, policy, and access to care. North America leads the market, bolstered by a strong pharmaceutical presence, high volumes of clinical trials, and rising biosimilar drug approvals. Substantial investment in R&D further supports this momentum; breast cancer receives the highest average annual funding among all cancers at $542.2 million, according to a 2023 review. Reinforcing this trend, Susan G. Komen announced $10.8 million in new research grants in 2025, accelerating innovation across early detection and treatment.
Building on this foundation of innovation, Europe holds a solid position in the global landscape. The region benefits from coordinated efforts like the European Commission Initiative on Breast Cancer (ECIBC), which promotes consistent, high-quality care across member states. For example, Germany’s national screening program invites women aged 50 – 69 for biennial mammograms, significantly strengthening early detection and preventive care.
This focus on structured healthcare expansion is echoed in the Asia-Pacific region, which is poised for the fastest growth during the forecast period. Regulatory reforms, wider acceptance of biosimilar, and a rapidly developing healthcare ecosystem are regional driving factors. China and India have emerged as key biosimilar hubs, enabled by efficient approval frameworks from the NMPA and CDSCO, respectively. Reflecting regional innovation, Indian startup Vara raised $8.9 million in 2024 to scale its AI-powered breast cancer detection platform.
Meanwhile, the Middle East and Africa are making gradual progress. Though still in earlier stages, efforts are underway to improve awareness, screening, and support services. In Saudi Arabia, the Zahra Breast Cancer Association plays a key role in advancing early diagnosis and patient care, signaling the region’s growing engagement in cancer control.
Together, these regional developments are shaping a more connected, accessible, and innovative global breast cancer market, paving the way for improved outcomes and equitable care worldwide.

Future Outlook: Advancing HER2-Targeted Therapies to New Generation Treatments
The market for HER2-targeted therapies is undergoing a strategic evolution, driven by an expanding pipeline and evolving clinical trials landscape. The future is moving from traditional approaches and treatment – monoclonal antibodies and antibody-drug conjugates (ADCs) to next-generation biologics, multi-target regimens, and digital-diagnostic integration.
The treatment paradigm of breast cancer is undergoing redefinition. Researchers are moving away from binary classification - HER2 positive and HER2 negative breast cancer. Earlier a high HER 2 overexpression was considered as the eligibility criteria for targeted therapies. However, advances in molecular profiling and clinical evidence are now indicating that breast cancer patients with low-to-ultralow HER2 expression levels can also benefit from such targeted therapies. These low and ultra-low HER 2 subsets represent ~45-60% of the total breast cancer diagnosis, representing a major patient pool that was earlier considered ineligible.
Clinical trials like DESTINY-Breast06 are at the forefront of this redefinition. The trial is aimed at evaluating trastuzumab deruxtecan (Enhertu) in HER2 low, hormone receptor positive, metastatic breast cancer patients. It showcased Enhertu to be superior to standard chemotherapy, signaling the drug’s applicability beyond traditional HER2 positive subgroups.
In longer terms, as HER2 positive breast cancer landscape evolves, companion diagnostics (CDx) are projected to become more sensitive and include wider HER2 classifications at a gradient scale. This in turn will enable tailoring of the treatment-intensity and drug selection across a wider continuum.
